CULTIVATING IMPLEMENT.

Application filed June is, 1925. Serial No. 37,413.

This invention relates to improvements in cultivator implements known asdisk harrows, and has'especial reference to a harrow of that type whichcomprises two pairs of gangs of rotary disk shaped cutters, one pair ofsaid gangs being arranged to operate at the rear of the other pair ofgangs.

The disks of each gang are journaled on bearings that are carried bysuitable yokes. Each yokeis connected to a gang frame capable of beingdrawn by horses or other suitable motive power.

In such machine the yokes are capable of being so set relatively to eachother, that the disks of the rearward gangs will pulverizeand level theground which hasbeen broken andthrown up by the disks of the forwardgangs. 1 5 l The construction of machines of this type has beenimprovedby providing yieldable connections in the gang frame, and of adjustableconnections for the gang yokes, so that the cutters may yield to theundulations of the ground surface, and whereby the gangs may be causedto operate in correct relation to each other.

WVhile such a machine may be used in following a line of draft in theunplanted the direction of travel of the disks can be regulated only bythe control constantly of the direction of travel of the horses.

The object of my present invention is to provide a cultivating implementof the kind described which is easy to operate and. con trol and whichis capable of so breaking the ground and of leveling same, and in whichthedirection of travel of the gangs, may be so controlled, that theground may be cultivated to a line close to the growing crop, the lineof the planted row may be easily followed. 7

Other objects of the invention are to provide means whereby the diskgangs may be raised and lowered, and may be retainedat raised positionwhen desired.

The aforesaid general objects, and also the more specific purposes ofthe'invention are accomplished by the new construction, combination andarrangement of parts shown in the accompanying drawings and described inthe following specification. The invention is defined in the appendedclaims.

The several parts of my improved cultie 'tively adjusted 7 positions,

My invention is embodied in a'machine of the form and construction shownin the drawings; such machine consisting of a frame structure designatedas the main frame,. axle bars for the said frame and which axle bars areof arched formation, steering knuckles for one of the axle bars, wheelsjournaled on the spindles of the axle bars, and on the spindles of theknuckles,

control devices for the steering knuckles, a

gang frame whose cross members are arched, yoked gangs ofdisks connectedto said gang frame, and adapted to be retained at relatween the gangframe and the main frame, a draw bar device swung from the front of themain frame, and loose connections begween the connector arms and thesaid draw The said main frame consists of side members 1 and 2, whoseforward portions are secured to a cross bar 3. The rear portions of saidframe are secured to a cross memher, which serves not only to retain thesaid side members but constitutes the rear axle bar 4. The outerportions of the axle bar are bent downwardly, and thence are turnedoutwardly and provided with spindles, upon which the wheels 5 and 6 arejournaled. To the forward portion of the said frame is secured a frontaxle shaft 7. The end portions of this shaft are turned downwardly andare provided with head blocks 7 to which steering knuckles 8 arejournaledon vertical pins 8*. On the spindles steeringknuckles the frontwheels 9 and 10 connector arms be of these IOU " nested" by a connectorbar 1 arm 8.

"op erate of the frame forms are journaled. Suitable braces 11 and 12extend from the .side members of the frame to the rear and front axlebars 4 and 7 respectively. A forwardlyextended head bar 14 which curedto thecc .ier oferossp V m V i snpportnponwhich a treebar 15, ispivotally retained by a loose pin 16. At the front end of head bar 14;,isloosely connected the tongue 17. A seat 18 for the operator'issupported on bars 19 that are securely connected to the main frameinembersi Arms 8" that extend from thekniickles 8 are loosely connectedbyja tie-rodQOQand a crank arm 8 extends laterally from each of saidknuckles. In bearingblocksQet, 24 which are secured to the side memberspf 25 arejournaled. Secured near each end of the shaft is a bell crankhaving a long arm 26 which is provided with foot stirrupQ'Y.

The upper ends ofthese arms are connected by pins42 looselyto a block 43 therefor securedto the cross piece 3 of the vehicle frame. Depending from the ends ofthe swiveled tre'ebar 15 are draw bars 45, from whose'lower portions,1inks4t6, extend to and are held inhooked engagement with hook tree 48is supported loosely by a hook link 49 to the draw bar 45. While thedraw of the main frame is at the tongue 17, the draw for the gang frameis at'the single trees. It is obvious that by having a plurality ofholes in the draw bar 45, and in. the hook plate 47, adjustments may be''so madethat the draw from the single tree may be had in conformity withthe blocks 50 of the main frame, the ends as gangs R.

ill" provided with a pawl that gangs are clearly shown in Figure 4, andI they are seen at the lowered or operative position, in Figure 2.'Tlie'rear 'portionsof the frame are provided with bracebars 36""; Handlevers 60 which are fulcrumed on a shaft 62 which has its ends securedtothe main frame, have the arms 63 and 64. "Each of these levers isprovided with-the usual latching means and" toothed sector '65. On ashaft 62 which has its ends secured to the main frame are journaled bellcranks having arms 61 and 63 Suspension members tend from the arms 63,63* to the gang frame and" are so arranged that the frame may be raisedor lowered by'manipn lation of one or both t heihand levers. Thesesuspension rods 66 66 have their upper .1

ends connected loosely "to the said arms 63, 63 and each have theirlower ends passed through support clips 36? and. '35 respec} tively ofthe gang frame. A detail of one of these suspension members is shown atFigure 5. washerfi? loose'on said rod underneath the clip, is retainedby a nut 68. Loose on said rod and above the clip is a seat ring 69 inwhich is seated a coil spring 70 whose upper end has engagement with acollar 71 retained on rod 66 by a set screw.

When the disk frame is at a lowered position, the springs .7 OeXert apressure against the clips 34 and 35 thereby providing a steadyingpressure on the frame. A coil spring 72 Whose forward end is secured tothe. frame member is connected to the short arm 64: of the hand lever,and'by its tension, it minimizes the amount of exertion required ofoperator in pulling the lever or levers rearwardly- (to raise j the gangframe). r V i lVhen transporting the 'ma'chine to the field that is to'be cultivated, the diskgangs are "at position suspended. At such sus-'pended position the levers 60 will have-been i iii) the gang frame anddisks are raised to sufficient height for the disks to clear the ground.The size and tension of the springs 7 2 may be varied and adjusted inconformity with the-requirements of the operator. angled positions ofthe disk gangs are plainly shown at Figure l, the gangs F being directedtoward, and the gangs B being directed away from the line of draft. Theangle of inclination of these gangs may be varied and'the disks may beworked at such depth in the soil as may be desired, according to thecondition and nature of the soil and of the growing crop.

Advantages of my invention are that the growing crop may be given thebenefit of the cultivating of the soil during the time from theplanting, and until same will have reached the stage of growth whenfurther cultivating for the season is unnecessary. With the gang framecross members arched to the height shown, the stalks are cleared withoutinjury. Cultivating of the soil to a line close to the growing stalks ispracticable, and such a clear view of the line of draft is had by theoperator, as the machine advances, that the work of cultivating is donerapidly and effectively, and without injury to the growing crop.

While the applied power for drawing the machine, is constant, and iseffective at all times to move the disk gangs the direction of thetravel of the disk gangs is under positive control and they may beproperly guided, according to the trend of the draft line, with onlyslight exertion by an operator of only ordinary skill.

The vehicle structure, and the draft structure, of the gang-mechanismsare so combined that while the applied power is fully effective inactuating the disks, the operator is supported at position where thecrop row is at all times easily visible, and from whence he may, witheasy effort, by simply guiding the vehicle by pressure of one or theother of his feet, in the stirrups 27, slightly to the right or left,cause the gangs to proceed on a line of travel whereby the soil iscultivated in conformity with the condition of the soil and with thevariation of the line of the crop row.

To vary the height at which the disks are to be operated in the soil, orfor raising the disks for the avoidance of obstructions, the operatorsimply uses the hand levers 60. By such control of theoperation, and thepositions of operation of the disks, no effort is necessary in theguidance of the horses.

The invention is embodied in a machine of the general proportions and ofstructure and detail as shown in the drawings, it will be understoodthat modifications may be made in the ,mechanical construction andarrangement of the several parts to suit the varied requirements themachine may be in The tended for. While the present machine is designedto beef width to cultivate on each side of a single row in thefield, itis apparent that by modification of the-main frame and the combiningwith same and its connected parts, additional sets of gangs, morethan'one row may be cultivated.

In the modification shown inFigure 6 will be seen the arrangement of theframe, and disk gang control members,-where one axle barZ1 and one pairof axled wheels only, are use What I claim as my invention, and desireto secure by Letters Patent, isc 1.
